PESSARY.

' SPECTFIGATION forming part of Letters Patent No. 606,565, dated June 2 8, 1898. Application filed December 2,1897. erial No. 660,508. (N0 model l Patented in England November 12, 1896, No. 25,473.

- invented a new and useful Improved Pess'ary,

(for which I have obtained Letters Patent in the following country, namely: Great Britain, dated November 12, 1896, No. 25,473,) of which the-following is a full, clear, and exact description. I

This invention relates to an improved pessary of the kind known as a spring-stem pessary, and has for its object to remedy the defects to which such instruments as now made are subject. 1

Heretofore the spring-stem of the pessary has sometimes been slotted and traversed by a cross-pin to limitits motion; but such construction is not effectual to prevent a certain amount of prej udical displacement of the cup Y or body portion of the instrument from its proper position andhas prevented the taking of the instrument to pieces for cleaning. In

other forms of. the same instrument which do admit of being taken to pieces the defect of liability to displacement of the cup or body portion in consequence of the movements of the body is much greater, and the component parts, being entirely separable, are liable to .be lost when the instrument is taken to pieces for cleaning. 7 I v The] object of the improvements is to enable the parts to be easily separated, so as to give sufficient access to the interior for the purpose of cleaning, without liability of loss by the multiplicity of loose parts, and at same time to prevent any relative motion of the cup or body portion and of the spring-stem which would permit of the displacement of the instrument from .its proper position'or other spring being permanently attached to the inner end of the stem and'the screw-cap, by

which the piston-like portion of the stem is retained within the bore, being confined between the piston-like head and the outer head of the stem, through which the elastic supporting-cords pass, so that by unscrewing the cap the spring and stem may be wholly Withdrawn and the interior portions of the instru ment may be thoroughly cleaned without f u rther separation of the parts. I

This improved construction is illustrated in the accompanying drawings, forming part of this specification, wherein Figure 1 is a longitudinal section, Fig. 2 an external view, andFig. 3 a top view, of the instrument, while Fig. 4 shows the springstem separately; and Fig. 5 is a section on line 5 5, Fig. 1.

a is the cup by which the uterus is received and'supported, perforated with the usual apertures and formed with a curved neck or body portion 1), adapted to the shape of the cavity in which it is received.

0 is the spring-stem, provided at the inner end with a head (1 of square section, fitting accurately in a bore 6 of corresponding form in the body portion 19, the stem 0 and bore 6 being curved inthe direction of their length tocorrespond to the curvature of the portion I).

' f is the spring con-fined between the inner I end of the stem and of the bore 6 and passed through'a hole or otherwise attached to an inner prolongation c of the stem. The stem 0 is of round section and slides through a cap g, which is threaded to screw upon the correspondingly-screwed end of the body portion b, so as to retain the piston-head d ofhaving one end secured to the stem, and a screw-cap on the end of the neck and through which the stem loosely slides, substantially as described.

2. In a pessary, the combination with the neck of the cup havingits end screw-threaded and provided with a bore square in cross-section, of a stem having a square head fitting in the bore of the neck and provided with a reduced extension beyond the head, a spring in the bore of the neck and having one end secured to the extension of the stem, and a screw-cap on the end of the neck and through which the stem loosely slides, substantially as herein shown and described.

Signed by me, the said ANNA MARY LONG- sHonn-Po'rTs, this 18th day of November, 1897.
